IMPROVEMENT IN DRAFT-EQUALIZERS.

Specification forming part of Letters Patent No. 209,296, dated October22, 1878; application filed July 6, 1878.

To all whom "it mag concern.-

Be it known that I, MACK Sco'rT, of Sidney, in the county of Ohampaignand State of Illinois, have invented certain new and useful Improvementsin Draft-Equalizers; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification, andin which Figure l is a plan View of my improved draftequalizer, and Fig.2 is a "ertical section of the same.

Corresponding parts in the two figures are designated by like letters.

This invention relates to certain improvements in draft-equalizers; andit consists of a transverse bar connected directly to the whiffletreeand front axle, and means for further equalizing the draft,substantially as hereinafter more fully set forth.

In the annexed drawing, A refers to the front axle of the running-gearof a vehicle. B is a transverse bar, preferably connected to the frontaxle, A, at each end, by chains a a, the bar B in turn being connectedor hooked to the draft-bar 0r whiffletree G by means of the hookeddraft-plate b.

Through the draft-bar or whiffletree 0 passes a headed bolt, 0, enteringan elongated slot, 0, in the pole or tongue D, by which combination andarrangement of parts the resistance of the load or weight is distributedover the points where the draft is applied-i. e., where the horses oranimals are hitched. The slot 0 in the tongue removes the draft from thelatter. The foregoing provisions are for two horses.

By this construction and arrangement of the parts of my device, theanimals pulling upon the whiffletree G are, by reason of the slot 0,caused to expend their force directly upon the front axle, A, as thereis not, nor can there be, any point in tongue D to share with axle A theforce expended in pulling forward upon the Whiffletree G.

This device is exceedingly simple, consequently cheap, and may beadopted at little expense.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- I The combination, with the tongueor pole D, having an elongated slot, 0, the bolt 0, fitting in saidslot, and the hooked draft-plate b, of the swinging crosspiece B androds a a, connecting with the axle A of the vehicle, substantially asshown and described, for the purpose set forth.

In testimony that I claim the foregoing as my own I afiix my signaturein presence of two witnesses.
